LP38693MPX-5.0

Linear voltage regulators, also referred to as linear regulators, are electronic devices that are widely used for powering electronic circuits, for instance. LP38693MPX-5.0 is a simplified low quiescent current, low-dropout (LDO) linear regulator manufactured by Texas Instruments. It was designed specifically to provide a low quiescent current and low output noise, making it ideal for embedded applications such as cellular phones, digital cameras and portable media players.

TheLP38693MPX-5.0 is a very versatile linear regulator capable of outputting up to 5.0V with a minimum of 0.3V dropout voltage.Its simplified design includes a precision reference, an error amplifierwith a 20MHz bandwidth, a negative-slope compensation circuitry and a PNP pass element. It has extremely low quiescent current of only 17μA at a 1.8V output voltage, making it an ideal solution for portable devices due to its extremely low power consumption.

The LP38693MPX-5.0 can be used in a variety of applications, where a linear voltage regulator is required. It is ideal for use in embedded systems, such as gaming consoles and media players, as it is extremely low power and can provide up to 5.0V of output voltage.

The working principle of the LP38693MPX-5.0 is quite simple. It follows a classic three terminal regulator circuit design. The voltage reference is connected to the input and the feedback pin is connected to the output. A voltage drop across the reference is then compared to the feedback voltage. If the feedback voltage is higher than the reference, the error amplifier will reduce the gate voltage of the pass element, thereby decreasing the output voltage.

The LP38693MPX-5.0 also features a slew rate of only 0.04V/μs, making it one of the most stable linear regulators available. This makes it ideal for regulating ripple and noise sensitive applications, such as medical and audio devices. Its load regulation performance is also quite impressive, capable of providing a 1% output voltage accuracy over 30mA load current.

Overall, the LP38693MPX-5.0 is an excellent choice for embedded designs requiring a low quiescent current, low-dropout linear regulator. It is capable of providing up to 5.0V with an extremely low quiescent current, making it perfect for battery-powered applications. Its excellent performance and features make it an ideal choice for almost any application requiring a low-dropout, low quiescent current linear regulator.
